HMC143 / HMC144 v05.1007 GaAs MMIC DOUBLE-BALANCED MIXER, 5 - 20 GHz Typical Applications Features Input IP3: +25 dBm The HMC143 & HMC144 is ideal for: Microwave Point-to-Point Radios LO / RF Isolation: 30 dB IF Bandwidth: DC to 3 GHz VSAT Small Size: 2.10 x 1.45 x 0.1 mm Functional Diagram General Description 4 The HMC143 chip is a minature double-balanced mixer which can be used as an upconverter or down- converter. The chip utilizes a standard 1m GaAs MESFET process. The HMC144 is identical to the HMC143 except that the layout is a mirror image designed to ease integration into image-reject mixer modules. Broadband operation and excellent isolations are provided by on-chip baluns, which require no external components and no DC bias. The design is similar to the HMC141/142 mixers but with an IF combiner in a double-balanced design, providing improved RF/IF isolation. These devices are much smaller and more reliable replacements to hybrid diode mixers. Electrical Specifi cations, T = +25 C, LO Drive = +20 dBm A Parameter Min. Typ. Max. Min. Typ. Max. Min. Typ.
